The 2007 models came with a cheaper design Rapid Reaction secondary and NO bearing at all in the primary clutch. This set also bolt on upgrades the 2007+ models from no bearing on shaft in the primary clutch to a bearing type primary, AND from a Rapid Reaction type secondary to a true Tied style secondary. On 2007+ models these help them engage and shift smoother same way as the 2006 came with the first time around.
Some other benefits of going to a Tied style secondary are they are fully rebuildable with a removable helix and are known for providing longer belt life/ being easier on belts. Comes correct for ready to bolt on and ride with weights and spring already in primary and helix and spring already in the secondary! CONDITION: Is new in box and ready to install.Add a map to your own listings.
